Management of liquid wastes on floating docks in the aspect of its impact on the environment

State of environment pollution in the area of operation of a floating dock was investigated. In the taken samples of liquid wastes, outboard water and bed sediments were determined values of their basic physical and chemical parameters as well as concentration of poly-cyclic aromatic hydrocarbons, butyl tin compounds ((Bt)3 SnCl, (Bt)2 SnCl2 , BtSnCl3 , (Bt)4 Sn), polychlorinated biphenyls (PCB 28, PCB 52, PCB 101, PCB 138, PCB 153, PCB 180) as well as heavy metals (Zn, Cd, Pb, Cu, Ni, Cr, Co, Fe, Mn, As, Hg).
